SWEET-Cat 2.0: The Cat just got SWEETer; Higher quality spectra and precise parallaxes from GAIA eDR3

S. G. Sousa, V. Adibekyan, E. Delgado-Mena +13

Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number o…

ESPRESSO high resolution transmission spectroscopy of WASP-76b

H. M. Tabernero, M. R. Zapatero Osorio, R. Allart +87

Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of two primary transits of the highly-irradiated, ultra-hot Jupiter-size planet WASP-76b. We inv…

A precise architecture characterization of the Men planetary system

M. Damasso, A. Sozzetti, C. Lovis +97

The bright star Men was chosen as the first target for a radial velocity follow-up to test the performance of ESPRESSO, the new high-resolution spectrograph at the ESO's Very-L…

Characterization of the K2-38 planetary system. Unraveling one of the densest planets known to date

B. Toledo-Padrón, C. Lovis, A. Suárez Mascareño +90

We characterized the transiting planetary system orbiting the G2V star K2-38 using the new-generation echelle spectrograph ESPRESSO. We carried out a photometric analysis of the av…

Revisiting Proxima with ESPRESSO

A. Suárez Mascareño, J. P. Faria, P. Figueira +88

We aim to confirm the presence of Proxima b using independent measurements obtained with the new ESPRESSO spectrograph, and refine the planetary parameters taking advantage of its…

Planetary detection limits taking into account stellar noise. I. Observational strategies to reduce stellar oscillation and granulation effects

Xavier Dumusque, Stephane Udry, Christophe Lovis +2

The radial velocity signature of stellar noise is small, around the meter-per-second, but already too much for the detection of Earth mass planets in habitable zones. In this paper…
